This database for the Hams Fork Cutoff of the Oregon/California National Historic Trail is comprised of digital topographic data and reference line established using point data gathered with Global Positioning System (GPS) technology which represents only an approximation of the centerline of the trails system. This database, which is to be used in conjunction with ArcView/ArcMap software, is provided to assist the user in analyzing the visibility of any proposed location(gound level) within 5 miles of the GPS reference line of the trails in order to evaluate effects to the landscape and setting of National Historic Trails in accordance with the National Historic Preservation Act and its implementing regulations at 36CFR Part 800. This data imparts no information relative to land ownership and conveys no right of access to any land. Legal access to or across private land requires permission of the landowner.

Purpose:

To assist in resource planning as it relates to the NHT setting.

All attributes created during the creation process were verified by displaying the lines in both the database and the spatial coverage, but no formal tests were performed.

Logical_Consistency_Report:

These data are believed to be logically consistent, though no tests were performed. Line geometry is topologically clean

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The data were created by delineating the boundary off a USGS 7.5 minute Topographic Map at 1:24000 scale. Therefore, the horizontal accuracy is assumed to be within National Map Accuracy Standards, with a horizontal accuracy of 45.6 feet at the 95% confidence level.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The data were delineated off a USGS 7.5 minute Topographic Map at 1:24000 scale. Therefore, the vertical accuracy is assumed to be within National Map Accuracy Standards, with a vertical accuracy of 11.9 feet at the 95% confidence level.

The Layer Files* have grouped the values into 4 groups: Not Seen Seldom Seen (1-5 times) Moderately Seen (6-21 times) Visible (seen >21 times)

*Layer files control the appearance of the data. These files may have to have the source(system path) adjusted to be usable.
